9. After the stack units have booted up, the stack formation is complete. Stack status can be verified
using 'show stack' command. In this output, D indicates a dynamic configuration. After you perform a
write memory, this display will change to S, for static configuration.

Stack construction method 2: Manual configuration
Description
With this method, user should configure every unit individually and enable stacking on each unit. Once
the units are connected together, they automatically form a stack. With this method, the unit with the
highest priority becomes the active controller, and ID assignment is determined by the sequence in
which user physically connects the units. The example used below is 12 units to form a linear stack.
Steps
Summarized steps:
• Configure highest priority on an intended active controller.
• Configure second highest priority on an intended standby controller.
• Configure 'stack suggest-id' on the units you chose to have a desired ID.
• Configure 'stack enable' on all the units and connect the units using stack ports.
Detailed steps:
1. Units should boot up using same software image.
2. On a unit intended to be the active controller, configure the priority unit at 255. Configure the standby
unit to be less than the priority (active) unit, for example, 240.
